Yes they do. Once you come up with some ideas for its use it really does work well. I have had other remotes inside buildings and fired them from outside with a hand aimed 600 and the tripod mounted camera in the street. The RT system really is a great system.

P.S. There is a caveat, if you have AF on and the camera can't aquire focus it won't take an image, but that is consistent with other remotes too.

Hmm...Like Neuro, I was thinking "trigger only" too...

Can you give more details on what you're doing? That sounds interesting!!!

Not that interesting really, just real estate. But like many of these features that don't initially seem much practical use, when you start thinking, or seeing what others are doing with them, some can really make nice differences. I recently got a WFT to take over from the EyeFi card I got so frustrated with, boy what a difference, never saw the value of a $500 option like that before but I wouldn't be without one now, though I was lucky and got a secondhand one for $160.

Anyway, nothing I do with the REL button on a 600EX couldn't be done with a $25 Yongnuo RF-602 (which is what I used to use) in addition to any remote flash setup, but the point of the RT system is that it is built in and just works. Cuts down on lots of remotes and batteries too!

My normal setup is this, it is next to impossible to light an entire above average sized property really well with less than fifteen or so small lights. So what I do is take fifteen or so shots and move one light and then blend the results. I have my camera set up on a tripod with the ST-E3-RT and SR-N3 connected, I then walk around with a 600 and point it at the building. When I want more lights than are available inside to shine through windows etc I will set up another 600 or two to do that at the same time, it just saves some time.

Neuro's idea of using it with a key light during portraits is also very good, and I will do that, if you frame loose and can activate the camera from a distance talking to or interacting with the subject I'd expect some interesting results, people are certainly much less stuff when you are not looking through the camera.

Too often we lose sight of the fact that photography is about capturing light, if we have the ability to take control of that light then we grow exponentially as photographers. More often than not the image is not about lens speed, sensor size, DR, MP's or AF, it is about the light.

One seller has it on amazon for 156usd, free shipping.Various sellers on ebay also have it for as little as 139, free shipping.Curiously, YongNuo's official ebay store (stores.ebay.com/hkyongnuophotoequipment) does not sell it yet.Unfortunately, all of them have ass-slow shipping from China. Delivery estimates to USA I'm seeing are consistently ~2-4 weeks (late Dec - Early Jan ETA).

If you guys are interested, maybe I'll do a teardown of the unit when it arrives.I got the fanciest shipping they offered (DHL supposedly 3-5 days) because I'm about to go on a trip, and I'm not really impressed with DHL's tracking updates. It's still stuck on "Saturday, December 14, 2013 Shipment information received -- SHENZHEN - CHINA, PEOPLES REPUBLIC". I barely ever have stuff shipped DHL though, so I don't know if their tracking always sucks or if that is indicative of a shipping problem.

I'm curious to see which RF transceiver chip they selected. I also wish i had access to a real ST-E3-RT available to compare the PCB with. I bet they almost completely ripped it off, lol.

it LOOKS pretty primitive -- most likely just a simple, single LED. A far cry from the AF grid that the 600EX-RT skeets out.

This probable is bad news for 5d3 users as that's what the 600rt's af assist beam is designed for - for the rest of us budget shooters like with "center point only" 6d I hope the simple design is good enough and certainly better than Canon's nil solution.

My finger is twitching on the click button for this. I don't get a grid pattern on my 600, I get four fat vertical lines. My YN622s project a neat little grid and work fine for how I use them, so I would imagine the new transmitter would be at least as good. I'm not usually an early adopter, but this one is getting to me.

The 600's beam patter changes depending on which AF point you have selected. Center point small pattern, auto goes to widest pattern and at least one more in between.

How about that, so it does. I use it on a 6D so of course I'm always using the center point
